Yoshi is a teacher who really wants his students to appreciate music in all of its forms. He presents his lectures in a format which gives you the most important information with examples of each term/artist/etc. Sometimes he rambles on and talks about things which have no importance on what he is teaching but it is still a fun experience. His exams have listening identifications, short response, multiple choice, and 1 or 2 essays. The essays are very generic allowing you to write about whatever you wish.
On a side note if he every invite you to a concert with a reception, attend.
